A survey was conducted to investigate the relationship between knowledge of perceived food safety and actual food purchase practices among parents of children under the age of seven (N=309) in 2005. The seventeen following perceived food safety items were included in the survey (bovine spongiform encephalopathy, foot and mouth disease, pathogenic avian influenza, swine fever, allergens, GMO, irradiated food, food poisoning bacteria, endocrine disrupter, antibiotics, food additives, carcinogen, natural toxin, agrichemical residues, place of origin, cultivation methods, and heavy metal) Most parents were highly concerned about investigating all food safety topics. Up to 90.0% of the participants recognized the importance of food safety. The public concern has caused a considerable decline in the demand for food afterreceiving news about food safety through mass media, Also, the majority of subjects required correct food safety information.

This study was carried out to investigate the applicability of the detection of central nervous system tissues (CNST) in beef by-products in retail market. Beef by-products including large intestine, brain, spinal cord, liver, lung, spleen and heart were purchased and tested for the presence of CNST using an ELISA method. The ELISA test was evaluated and showed a high correlation coefficient by a standard curve (R value = 0.999). Based on the analytical instruction, the positive indication of the CNST contamination of brain and spinal cord was detected above 0.1% but large intestine, liver, lung, spleen, and heart was negative. Result suggests that the ELISA method is applicable to a real meat system and may provide a method to ensure confidence for consumer against bovine spongiform encephalopathy (BSE).

Concern about food safety among consumers is very high at the moment, because many problems related to food safety have occurred, such as Bovine Spongiform Encephalopathy (BSE). To improve consumers' reliability about food safety issue, government in every country have tried to set various food policy, and the Korean government has also tried to set consumers at ease about their diet, for instance, food traceability system. The aim of this study is to define consumer perceptions and intention to participation for solar salt traceability system. As the results, consumers generally have positive perception about solar salt traceability system, and the study identifies that attitude, reliability and availability significantly influence intention to participation for solar salt traceability system.

Bovine spongiform encephalopathy (BSE) has become an important concern in food safety. Until now, 36 cases of BSE have been detected in Japan. Control programs have led to a decrease in the annual numbers, and Japan has now been categorized as a "controlled risk" country by the World Animal Health Organization (OIE). In spite of a worldwide decrease in the number of BSE cases, sporadic occurrences of atypical BSE cases have been reported. In Japan, 2 atypical BSE cases were confirmed. A Japanese L-type-BSE (BSE/JP24) has exhibited transmissibility to bovinized transgenic mice (TgBoPrP) it has a shorter incubation period than that of classical BSE. Although the origin of atypical BSE is obscure, risk analysis of newly emerged BSE prions of cattle and humans is required.

소 해면형 뇌증(Bovine Spongiform Encephalpathy; BSE)은 일명 광우병(mad cow disease)이라고도 불리우는 새로운 해외 가축전염병이며, 세계적인 희귀질병으로 아직까지 확실한 병인체가 밝혀져 있지도 않으며, 그렇기 때문에 면역 혈청학적 진단방법도 확립되어 있지 못할 뿐만아니라 예방백신의 개발 또한 불가능하기 때문에, 일단 감염되어 발병되면 치료대책 없이 100$\%$ 폐사되는 세기의 불치병이다. 본 편에서는 소 해면형 뇌증(BSE)과 관련, 국제수역사무국(OIE) 총회에 보고된 영국정부의 공식보고 자료(Dept of Health, MAFF, 1989) 및 최근의 보고자료(1994, 1995)를 기본으로 하고, 각 회원국의 보고자료(Animal Health Status in Member Countries)와 전산화 역학정보 자료(Handistatus) 등을 근거로 하여, 소 해면형 뇌증이 세계적으로 처음 보고된 1986년 이래 최근 (1996년 3월)까지의 해외발생 역학정보를 수집 분석하고, 아울러 최근 전염병 및 해충의 효과적인 관리를 위하여 새롭게 정립되어 가고 있는 위험도 분석(risk analysis)의 개념을 도입하여, 우리나라에 있어서의 수입 쇠고기의 안전성 문제와 국내에서의 소 해면형 뇌증의 발생 가능성 등에 관하여 고찰해 보고자 한다. 결론적으로 소 해면형 뇌증은 현재 영국(그레이트 브리튼, 북아일랜드 등)에서 가장 크게 문제시 되고 있으며, 유럽 일부국가, 영국으로부터 소를 수입한 극소수의 국가에서 문제가 되었을 뿐, 영국 등 발생국가로부터 소와 쇠고기를 수입하고 있지 않는 우리나라에 있어서는 수입 쇠고기의 안전성에 문제가 없으며, 소 해면형 뇌증이나 양 스크래피의 국내 발생 가능성도 현재로서는 무시할 수 있을 정도로 극히 희박한 것으로 평가된다.

The features of seizure-related brain injuries in rats poisoned i.p. with diisopropylfiuorophosphate were investigated. Pyridostigmine bromide (0.1 mg/kg) and atropine methylnitrate (20 mg/kg), which are centrally inactive, were pretreated i.m. 30 min and 10 min, respectively. before diisopropylfluorophosphate (10 mg /kg, $2LD_50$) poisoning to reduce the mortality and eliminate peripheral signs. Diisopropylfluorophosphate induced severe limbic seizures, and early necrotic and delayed apoptotic brain injuries. The necrotic brain injury, which was closely related to seizure intensity, was exerted as early as 1 hr predominently in hippocampus and piriform cortex. showing spongiform change (malacia) of neurophils in severe cases, in contrast to a typical apoptotic (TUNEL-positive)pattern after 12 hr in thalamus, and a mixed type in amygdala. Nitric oxide content in cerebrospinal fiuid significantly increased after 2 hr, reaching a maximal level at 6 hr. Pretreatment with $_L-N^G$-nitroarginine, an inhibitor of nitric oxide synthase, reduced nitric oxide content and attenuated only apoptotic brain injury in all four brain regions examined without affecting seizure intensity and necrotic injury. Taken together, early necrotic and delayed apoptotic brain injuries induced by diisopropylfiuorophosphate poisoning in rats may be related to seizure intensity and nitric oxide production, respectively.

Toxoplasma gondii atypical type II genotype was diagnosed in a pet peach-faced lovebird (Agapornis roseicollis) based on histopathology, immunohistochemistry, and multilocus DNA typing. The bird presented with severe neurological signs, and hematology was suggestive of chronic granulomatous disease. Gross post-mortem examination revealed cerebral hemorrhage, splenomegaly, hepatitis, and thickening of the right ventricular free wall. Histologic sections of the most significant lesions in the brain revealed intralesional protozoan organisms associated with malacia, spongiform changes, and a mild histiocytic response, indicative of diffuse, non-suppurative encephalitis. Immunohistochemistry confirmed the causative organisms to be T. gondii. DNA isolated from the brain was used to confirm the presence of T. gondii DNA. Multilocus genotyping based on SAG1, altSAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico markers demonstrated the presence of ToxoDB PCR-RFLP genotype #3 and B1 gene as atypical T. gondii type II. The atypical type II strain has been previously documented in Australian wildlife, indicating an environmental transmission route.

Objectives: This study investigates whether Korean news media pay more attention to emerging diseases than chronic ones, and whether they closely follow the changes in the magnitude of health risks of chronic or well-known diseases. These two features are expected to appear as the result of surveillance function served by health journalism that should be the main source of the public's risk perception. Methods: The number of stories published in 10 newspapers containing the words, 'SARS,' 'Bovine Spongiform Encephalopathy,' 'Avian Influenza,' and 'Influenza A virus' was compared with the number of stories on chronic or wellknown diseases. We also counted the annual number of stories, published in a 12-year period, containing following terms: 'cancer,' 'diabetes,' 'hypertension,' 'pneumonia,' and 'tuberculosis.' The number was compared with the actual mortality of each disease. Results: Although cancer represented the primary cause of mortality, the newspapers covered key emerging diseases more than cancer or other well-known diseases. Also, media coverage of 'pneumonia' and 'tuberculosis' did not vary in accordance with changes in the mortality of each disease. However, the news media coverage did vary in accordance with the mortality of 'cancer,' 'diabetes,' and 'hypertension.' Conclusions: Korean health journalism was found to have both strong and weak points. The news media reduced the relative level of attention given to pneumonia and tuberculosis. Bearing in mind the major influence of news coverage on risk perception, health professionals need to be more proactive about helping to improve Korean health journalism.
